Air show officials aren't estimating how many people will attend Saturday's event, but say between 70,000 and 80,000 people typically attend over the weekend.

The air action begins at 10:45 a.m.; it's already warm, and there's not a cloud visible in the sky. On the schedule: The 6-Jet Patriots Team, Oregon Air National Guard F-15, and U.S. Air Force F-16 Demonstration, among others.

Hamburgers and chicken are grilling and the Minidoka Swing Band is, well, swinging. And their smooth, old-fashioned tunes caught 2-year-old Jerry Jones III or J.J.'s attention.

Dressed in an orange T-shirt and hat, J.J., mesmerized by the band, stopped and let go of his cousin 8-year-old Jack Graham's hand. J.J. started to dance, a fast series of little bounces in a circle, a bit ahead of the song's beat.

J.J.'s attending this year's show with his father, Jerry Jones Jr., and grandfather, Jerry Jones Sr., along with Jack and his father George Graham, 40, who came up from Eugene.

The group decided to head to the show for a boy's day. "We came to bring all of us together," said Jones Jr., 34, who lives in Beaverton. He added that they're looking forward to seeing the military displays and the tricks in the sky.

"He likes playing with airplanes at home," Jones Jr. said of his son. "Here, he can look at them, see them, play in them -- and then -- see them fly by."

Jones Jr. asked his son what the planes are going to do. After a momentary pause, J.J. made a grunting, "Vroooooom," and waved his arm wildly toward the sky.

The group erupted with laughter.

Laughing 72-year-old Jones Sr. said, "I am just excited to see the planes -- and see the kids get excited."
